In view of that consciousness is (or seems to be) the most ill-defined of
any commonly kept in mind and debated concept, you might be well of
referring to your idea as something like a 'cosmological (spacetime
topological) coordinates correlate of consciousness'.
Thereby you might avoid adding to the confusion. After all, the
interpretation of consciousness that is to us most relevant and of most
primary importance is inevitably a simple neuropsychophysiological one.
However, your interpretation (or one closely similar to it) would go towards
reinforcing the peripheral (or philosophically complementary) frame for this
simple neuropsychophysiological explanation for "consciousness".
(By the way, at the other end of this 'philosophical complementarity' there
are some evolution theoretical considerations.)
